Echo: libsoup3: security update to 3.6.6-1+e8

high Tenable Self-Hosted Container Security Plugin ID 473205

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - A flaw was found in libsoup. The soup_uri_decode_data_uri() function incorrectly treated base64 data-URI
 payloads as NUL-terminated strings when calling g_base64_decode_inplace(). If the percent-decoded payload
 contained embedded NUL bytes, the decoded length could remain uninitialized and be used as the size of the
 returned GBytes. This can lead to an out-of-bounds read or application crash when processing a crafted
 data URI. (CVE-2026-102555)

Solution

Update the libsoup3 library and its related packages to version 3.6.6-1+e8 or later.
